This patch add new SM5502 MUIC(Micro-USB Interface Controller) device by using
EXTCON subsystem. The extcon-sm5502 driver is capable of identifying the type
of the external power source and attached accessory. An external power sources,
such as Deticated Charger or a standard USB port, are able to charge the battery
in the smart phone via the connector.

Previously we would do a regulator get against the main Arizona device
to obtain the MICVDD regulator. Arizona is an MFD device and normally
MICVDD will be supplied by one of its children (the arizona-micsupp
regulator). As devres destruction for the MFD device will run after all
its children have been destroyed, the regulator will be destroyed before
devres calls regulator_put. This causes a warning from both the
destruction of the child node, as the regulator is still open, and from
the put of the regulator as the regulator device has already been
destroyed.
A simple fix here is to get the regulator against the extcon device
itself such that devres runs when the child is destroyed. This has the
additional benefit that if for some reason the extcon driver is unloaded
the regulator reference won't hang around until the MFD is unloaded.

didn't change the signature of altera_jtaguart_console_putc() to take a
pointer to struct uart_port instead of struct console, breaking the
driver's console support and leading to the following warning:
> drivers/tty/serial/altera_jtaguart.c: In function 'altera_jtaguart_console_write':

Fix this by adjusting the signature of altera_jtaguart_console_putc()
accordingly.

`ni6527_reset()` is called to reset various registers when the device is

The "edge detection interrupt" subdevice supports the
`INSN_CONFIG_CHANGE_NOTIFY` comedi instruction which is only supported
by one other driver. The `INSN_CONFIG_DIGITAL_TRIG` comedi instruction
is more flexible as it supports both edge and level detection, but is
not currently supported by this driver.
Add partial support for `INSN_CONFIG_DIGITAL_TRIG`, but only for edge
detection. Make use of the `ni6527_set_edge_detection()` used for
`INSN_CONFIG_CHANGE_NOTIFY`, but add a parameter holding a mask of the
rising and falling edges to be updated and preserve the unmasked edges
when updating.

This driver currently inverts the outputs for the DO (digital output)
subdevice for some of the boards it supports, indicated by the
`invert_outputs` member in the board-specific data being initialized to
1. It seems this driver shouldn't really be inverting outputs for these
boards at all, but has done so since the driver was first written back
in October 2006. I've had confirmation that for the PCI-6515 at least,
the output voltage levels are opposite to the values set by the user
program.
The driver by Jon Grierson originally supported only PCI-6514 and
PXI-6514 (and was originally called "ni_6514"). The driver was based on
"ni_6527", which is where the inversion of outputs appears to have come
from. Over a period of a few days, the driver was enhanced by Frank
Mori Hess to support other boards. Some of these plainly didn't require
inverted outputs and some guesswork was used to decide which boards
should have inverted outputs. Some of the boards in question are
described in the manual as having "Sink Outputs" and others are
described as having "Source Outputs", but this does not correspond in
any way with which boards are marked as having inverted outputs, so the
criterion that Frank used is a bit of a mystery!
Change the driver so it doesn't invert the outputs of these by boards by
default, but add a module parameter, "legacy_invert_outputs", that can
be set to 'true' to restore the old behaviour. Also rename the
`invert_outputs` member of `struct ni_65xx_board` to `legacy_invert`.

GHES currently maps two pages with atomic_ioremap. From now
on, NMI is architectural depended so there is no need to allocate
an NMI page for platforms without NMI support.
To make it possible to not use a second page, swap the existing
page order so that the IRQ context page is first, and the optional
NMI context page is second. Then, use HAVE_ACPI_APEI_NMI to decide
how many pages are to be allocated.

Currently APEI depends on x86 architecture. It is because of NMI hardware
error notification of GHES which is currently supported by x86 only.
However, many other APEI features can be still used perfectly by other
architectures.
This commit adds two symbols:
1. HAVE_ACPI_APEI for those archs which support APEI.
2. HAVE_ACPI_APEI_NMI which is used for NMI code isolation in ghes.c
file. NMI related data and functions are grouped so they can be wrapped
inside one #ifdef section. Appropriate function stubs are provided for
!NMI case.
Note there is no functional changes for x86 due to hard selected
HAVE_ACPI_APEI and HAVE_ACPI_APEI_NMI symbols.

This commit abstracts MCE calls and provides weak corresponding default
implementation for those architectures which do not need arch specific
actions. Each platform willing to do additional architectural actions
should provides desired function definition. It allows us to avoid wrap
code into #ifdef in generic code and prevent new platform from introducing
dummy stub function too.
Initially, there are two APEI arch-specific calls:
- arch_apei_enable_cmcff()
- arch_apei_report_mem_error()
Both interact with MCE driver for X86 architecture.
